Checklist of the butterflies (Lepidoptera: Papilionoidea) of Montenegro Author Franeta, Filip text Zootaxa 2018 2018-03-08 4392 1 128 148 journal article 30557 10.11646/zootaxa.4392.1.6 1e43d07c-6f95-4816-8a17-3c271afe1356 1175-5326 1195491 ED61AE1A-FF8A-4B49-8A78-7E5EE7296A77 Leptidea duponcheli (Staudinger, 1871) —Observed in Montenegro only by Müting (1973) from Miločer, near Budva where it was reported as common. Interestingly L. sinapis was not recorded by Müting from the same locality, casting doubt on the correct identification. The author has never observed L. duponcheli in the aforementioned area, only specimens of the L. sinapis complex. The species was also reported by Sobczyk & Gligorović (2016) . However, Mr. Sobczyk has provided photographs of collected specimens and it was confirmed that the sampled material belonged to the L. sinapis complex. It is possible that the specimens observed by Müting (1973) also belonged to the summer generation of L. sinapis , as both species are very similar in the 2nd generation, and not always easy to separate. Without the possibility of verifying Müting’s observations L. duponcheli is retained in the current list, but needs to be confirmed.
